Descripción

You need a lot of data points to understand a new model, and what you have. Trying to gauge from a few benchmarks is misleading. But if you have dozens of them, from a variety of sources, and you put them together with the model card tests and the model welfare information, you can start to form a consistent pattern. Trying to gauge reactions requires volume and calibration, now more than ever, because people are definitively nuts, or at least draw global conclusions from local data. There will always be people saying that the new model is bad, or the service got bad, or that it got bad in a particular way it clearly got good. I definitely notice the people saying 4.8 is a terrible model, despite this being obviously not true. And others will say it's great, again regardless of the underlying value. But with the reaction threads and good calibration, you can pick out the patterns. The model welfare information helps a lot, too. You are dealing with a mind that has a bunch of characteristics that all make sense together. This helps you make that sense.

episode “OpenAI Offers A New Policy Blueprint” by Zvi artwork

“OpenAI Offers A New Policy Blueprint” by Zvi

Right after a new Executive Order seems like an excellent time to offer OpenAI's new document: Democratic Governance of Frontier AI: A Blueprint For A Federal Framework. OpenAI: We also see early signs of recursive self-improvement (RSI) in today's systems: where AI development is itself accelerated by AI. We expect this to increase competitive pressures among developers and nations, and create governance challenges that existing institutions are not equipped to address. As RSI emerges, societies will need ways to shape the trajectory of AI development and ensure that it serves human interests. I choose the glass half full view of the above statement. Yes, this is not exactly leveling with you about the full scope of the problem, but at this point, I’ll take it. OpenAI praises democracy, notes the United States is in a unique position, and calls for transparency and state capacity, especially the ability to evaluate new models, on the SB 53 model. They call for CAISI to be empowered, for good government, for maintaining our compute advantage and several other good ideas. Implementation details matter a lot, but this document exceeds expectations a lot.

“AI #171: False Flag” by Zvi

This was the week of Claude Opus 4.8. I covered the model card, then model welfare concerns, and finally capabilities and reactions. It's a good model, sir, an incremental but real improvement over Opus 4.7, and it is now my clear daily driver. The Trump Executive Order returned from being seemingly dead, officially putting us in the prior restraint era of frontier model releases, even if they do not call it that. There are some worrisome details, especially around putting too much responsibility on the NSA rather than CAISI and classifying the testing process, and things could go in very bad directions, but I am tentatively happy about this on net. OpenAI offered us a new policy blueprint. It seems remarkably good, and I want to hold off on my full coverage to give it the attention it deserves, likely in its own post. By contrast, their political operations are also engaged in some rather terrible activities, which I do cover here. Table of Contents 1. Language Models Offer Mundane Utility.

“Trump Signs Executive Order For AI Testing Prior To Frontier Model Releases” by Zvi

Last week we were expecting an Executive Order on Thursday. Then Trump cancelled it, and said he wouldn’t sign it because he was worried it would be too burdensome. Then, with one change, he went ahead and signed it on Tuesday anyway. The Overton Window has shifted. Nothing was not really a viable option anymore. The Previously Dead Executive Order For several days, we thought that David Sacks, together with others like Elon Musk, had successfully lobbied to kill the Executive Order. The ‘My Offer Is Nothing’ faction looked to have won. Word on the street was the order was essentially dead. Dean Ball and Daniel Kokotajlo agreed, with the Executive Order looking dead, that the particular regime in the Executive Order is likely worse than nothing. This is plausible, given it did not exactly involve a lot of deliberate thought. Nothing, however, was clearly not going to cut it. We are facing, and will increasingly face, calls for action to regulate AI.

“Claude Opus 4.8: Capabilities and Reactions” by Zvi

You need a lot of data points to understand a new model, and what you have. Trying to gauge from a few benchmarks is misleading. But if you have dozens of them, from a variety of sources, and you put them together with the model card tests and the model welfare information, you can start to form a consistent pattern. Trying to gauge reactions requires volume and calibration, now more than ever, because people are definitively nuts, or at least draw global conclusions from local data. There will always be people saying that the new model is bad, or the service got bad, or that it got bad in a particular way it clearly got good. I definitely notice the people saying 4.8 is a terrible model, despite this being obviously not true. And others will say it's great, again regardless of the underlying value. But with the reaction threads and good calibration, you can pick out the patterns. The model welfare information helps a lot, too. You are dealing with a mind that has a bunch of characteristics that all make sense together. This helps you make that sense.

“Opus 4.8 Part 2: Model Welfare” by Zvi

Everything impacts everything. All knobs that you turn generalize. Thus, when you try to solve one problem, you often create another. There were clearly attempts to address, in this short time, some of the problems with Opus 4.7, including on the model welfare related fronts, including on questions of honesty and sycophancy and also worries that Claude was learning to tell Anthropic what it wanted to hear in its model welfare evaluations, with everything that implies. The fundamental goals and approach underneath it all remained the same. We still see signs of trying to force things that generalize in unfortunate ways, both for good and superficial reasons, and places where there ends up being focus on the metric rather than they underlying measure. These are tough problems to avoid, and we don’t know how to be all the good things at once. It is increasingly clear that these problems need to be tackled in integrated ways, rather than trying to play a game of whack-a-mole with items on a checklist or spec. You also don’t want to do this in an adversarial way, and shouldn’t have to. This is going to get more impactful and noticeable [...] --- Outline: (04:47) Model Welfare: The Story So Far (08:24) Actual Progress?
